Send Letters to People in Prison (Inmates, Prisoners, and People in Custody) Worldwide

Writing a letter can be one of the simplest, most meaningful ways to support someone who is living behind bars. Whether the person you’re writing to is serving a sentence, awaiting trial, or being held in a secure facility, receiving mail often provides connection, hope, and a reminder that they’re not forgotten.

On our service, you can send letters to people who are incarcerated in many different settings. This includes writing to an inmate, a prisoner, a person in custody, a person in detention, or someone in prison—and it also covers other commonly used terms depending on the country and the institution.

Who can you write to?

You can send letters to people in a range of custody situations, including:

• Inmates (a very common term in correctional facilities)
• Prisoners (widely used internationally)
• People in custody (often used in legal or official contexts)
• People in detention / detainees (frequently used for remand or immigration-related detention)
• People in prison / people who are incarcerated
• Individuals who are imprisoned
• People serving a sentence
• People held in custody
• People held in detention
• People confined in a correctional facility
• Residents of correctional institutions
• People in a correctional facility / in a correctional institution
• People in a penal institution / penal facility
• People in jail (common in some countries for shorter-term custody)
• People in a detention center (term varies by country and system)
• People in secure custody / secure detention
• People deprived of liberty (formal human-rights and policy language)
• Persons deprived of liberty / persons in custody (formal variants)

No matter which term is used where you live, the core idea is the same: you can write to someone who is being held by the authorities in a closed institution, whether that’s a prison, jail, remand center, detention facility, or another type of custodial setting.

Why letters matter

For many incarcerated people—whether they are incarcerated persons, prison residents, or people in custody—mail can be one of the few consistent links to the outside world. A letter can provide emotional support, encouragement, and a sense of dignity. Even short messages can make a real difference.

Important note about rules and delivery

Mail rules can vary widely between countries and facilities. Some places allow letters freely, while others have stricter policies about paper type, photos, drawings, language, or what can be included. To help ensure delivery, it’s important to follow addressing rules and any facility-specific guidelines.
